Whole Process Method Of Air Leakage Inspection For Keyed Air Expansion Shaft

Users who know the key-strip air expansion shaft will definitely encounter the appearance of air leakage. You may be at a loss about its air leakage question. When you look at the repair plan in the explanation book, but still can’t handle it, the following Jichang air shaft The author will provide you with the best solution for this difficult question one by one.

Now that you want to find the reason, you might as well perform manual disassembly first to check the generalized cause of the air leak. Today, the editor will carefully tell you about the disassembly of the air shaft and check the installation process: first disassemble Air shaft process

Before disassembling, take a look at the structure diagram of the key-type air expansion shaft, and then perform manual operation. First press the steel head of the air expansion shaft inflating nozzle, release the compressed air in the air expansion shaft, and then remove it Inflatable mouth. Use an iron wire with a diameter of 1-1.2mm to pass through the small holes on the key strip along the circumferential direction of the air expansion shaft, and the same circumferential direction is a group; all the key strips are fastened. Avoid when pulling out the airbag. The health bar falls into the aluminum alloy roller, which can also facilitate the installation of airbags. Take out the positioning screws (M6 hexagon socket screws) and positioning sleeves that fix the two ends of the aluminum alloy roller and the air expansion shaft.
It is necessary to process a screw for the pin puller, and install the air shaft on the lathe. Usually, the touch surface between the inflatable end of the key-type air shaft and the aluminum alloy roller will be coated with sealant. You should Use a gas torch and heat it first. When heating, other parts should be cooled to avoid deformation of the aluminum alloy roller. Pull the end after the sealant softens, because the airbag is connected to the inflatable end, the airbag will be easily pulled out.
Cause analysis and treatment of the problem of air swelling axis

Air leakage at the inflation nozzle of the air shaft: check the inflation nozzle, if the inflation nozzle is normal. Strengthen the seal at the touch surface of the inflation nozzle and the inflation tip. The inflation nozzle is abnormal and the inflation nozzle should be replaced.

Other parts of the air shaft are leaking: Check if there are any damages on the surface of the airbag. If there is, you need to replace the airbag. Furthermore, it is to check whether there is air leakage between the airbag and the inflating end. If there is air leakage, it should be strengthened.

The key strip of the air expansion shaft is detached: Check whether the key strip and the key strip discriminating seat are combined normally, and whether the base is damaged. Repair the base and fasten the key bar to the base.
